VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 467,376, dated January19, 1892.

Serial No. 384,894. (No model.)

To aZZ whom it may concern:

Be itknown that I, THOMAS S. KING, of Cincinnati, in the county ofHamilton and State of Ohio, have invented a new and useful Improvementin Vehicle-Springs, of which the following'is a specification.

My invention is an improved spring, which may be employed for supportingvehicle bodies or seats, or in other arrangements where such springs aredesired; and it consists in certain novel constructions and combinationsof parts, as will be hereinafter described, and pointed out in theclaim.

In the drawings, Figure 1 is a side view of the spring expanded. Fig. 2is a side view of the spring, showing the same shortened, as whenconsiderably compressed; and Fig. 3 is a cross-section.

The spring is shown as made from a single strip of metal bent to thedesired shape and joined at its ends by riveting or other suitable meansof fastening. I bend the strip to form the upper and lower portions A A,which may be called the side sections. These side sections are in formand construction alike, except that in one of such sections the ends ofthe strip are secured at d by riveting or in other suitable manner. Thesections A are each formed with the flat or straight central portion B,the bends O at the ends of the portion B, such bends C projectinginwardly from the portions B, the outwardly-curving bends D. extendingfrom the inner ends of bends O, and the inwardlycurving or reverse bendsE extending from the bends D, the ends of such sections A beingconnected. As shown and preferred, the upper and lower sections areintegral, and are connected by the end portions F, which are bent toform the rounded endsf, the outwardly-curved bends f, and the drawn-inportions f at the juncture of the end portions and the side sections.These drawn-in portions f come together when the spring is considerablycompressed, and so shorten the spring when it is supporting the greatestweight. It will be seen that when a light load is on the spring theentire length of the sections and the end portions F are in full play.Now when a considerable weight is supported on the spring the latter iscompressed and the contact-points are brought together, as shown in Fig.2, and the spring is consequently shortened, thus adding to itscapacity, as will be readily understood. The central flat portions Bfacilitate the application of the springs to wagon bodies, seats, orother parts, and avoid the necessity of using head-blocks or other barsin securing the springs. The inward bends C, projecting downward fromthe upper section A and upward from the lower sect-ion, increase Whatmay be termed the height of the spring and co-operate with the bends D Ein providing a strong easy spring. Where desired, the springs may bemade of several leaves, additional leaves being provided according tothe Weight the spring is designed to support, the said additional leavesto be somewhat shorter than either side or half of the spring andproperly fitted to the spring, so they will Work easily the same as anyordinary leaf-spring. These springs may be attached or secured to seats,spring-bars, body of vehicle, or axle by bolts through holes in theupper and lower portions of spring, or by means of clips, such as areused ordinarily in fastening any flat spring in place.

Having thus described my invention, what I claim as new is As a new andimproved article of man ufacture, the spring herein described, composedof the sections A, having the central flat or straight portions 13, thebends O, projecting inwardly from the opposite ends of said fiat centralportions 13, the bends D, curving outwardly from the inner ends of thebends O, the reverse bends E, extending from the ends of the bends D,and the connecting end portions F, connecting the outer ends of thesections A, all substantially as and for the purposes set forth.

THOS. S. KING.
